Problems

• Bluejacking
• Bluesnarfing
• Bluespamming
• Low data rate
• Only point to point

Conclusion

• Bluetooth technology encompasses several key
  points that facilitate its widespread adoption
• Its specification is publicly available and free
  .
• Its short-range wireless capability allows
  peripheral devices to communicate replacing
  cables that use connectors.
• Bluetooth supports both voice and data.
• Bluetooth uses an unregulated frequency band
